and releasing boats and has for an object to provide means whereby the boat may be automatically released by the action of the water in case of a vessel sinking; or by which the boat may be quickly released by hand whenever desired; and the invention consists 'in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawing Figure 1 is a side view of a small boat with my improvements applied.

. Fig. 2 is a detail elevation partly in section of one of the improved devices with the parts in full lines in position to secure a boat and in dotted lines in position to release the boat.

The ordinary davits now in use on vessels are such that the small boats are lashed tightly thereto and can only be released by untying the ropes and in case the vessel should suddenly sink the small boats would be carried down with it.

By my improvement I provide means whereby in case the vessel sinks the action of the water will release the small boat through the aid of a buoyant weight or float and by preference this weight or float is supported outside of the small boat and forms a part of the means for detachably or releasably securing the small boat to the vessel. I

In the construction shown I provide the boat with seats for engagement by the bolt of the fastening means. These seats are preferably the upturned outer end A of S shape links A whose inner upper ends are engaged over the gunwale of the boat as best shown in Fig. 1. The bolt B is jointed at one end to a frame C and rests in the seat A and has its other end releasably held by a latch D which is secured in engagement with the bolt B by the weight of the buoyant weight E. The latch D is pivoted at D between its ends to the frame C, is adapted at one end D to hold and release the bolt B and is connected at its other end D by the line or rod F with the weight E which may be a heavy block of wood or other material lighter than water or may be a hollow metallic body. The weight is preferably inclosed in the hollow casing G closed at the top eX- cept for the opening intended for the passage of the rod and also to afford a passage for the air and the bottom being closed by the perforated plate G, the closing of the casing at the ends operating to exclude dirt and the like. The casing is connected at its upper end by chains II or otherwise with the frame C and is secured at its lower end by a lashing I to the vessel, the casing thus forming a guide for the weight, and also a part of the device for releasably securing the boat.

Manifestly, when the parts are in the posi tion shown in Fig. 1, the boat will be securely held and may be quickly released by lifting up the end D of the latch Whenever desired; or, if the vessel should sink, the weight raised by the water will instantly free the latch and the boat will be freed as desired.

It will be noticed the buoyant weight or float E is supported independently of the boat and is operated on by the water outside of the boat and in no way interferes with the use of the boat and in no degree limits or restricts the capacity of the boat. It will also be seen that the improved devices can be used with the boats now supplied to vessels and will require no change in the construction of such equipment of vessels.

I claim 1. A boat securing and releasing apparatus, comprising a frame, a bolt jointed thereto at one end and free at its other end, a latch pivoted to the frame and engaging at one end with the bolt, a buoyant weight connected with the other end of the latch, a casing for said weight, and means connecting the casing with the frame, substantially as set forth.

2. The combination of a vessel, a boat thereon, a casing connected at one end with the vessel, a frame connected with the other end of the casing and having a bolt, and a latch for securing the same, and a buoyant weight in the casing and connected with the latch, substantially as set forth.

3. The combination with a boat of means for securing the same, and having releasing devices, a casing outside of the boat and suspended from said securing means and a float in the casing and connected with the releasing devices for operating the same.

4. A boat securing and releasing apparatus comprising a frame, a casin suspended from the frame, a bolt and latc carried by the frame, and a float in the casing and connectthe frame with the boat, a latch for holding 10 ed with the latch, substantially as set forth. said bolt, connections between the frame and 5.
